The given equation in standard form is:

$3x+5y=7$

Step-by-step explanation:

Given equation is:

$x = -\frac{5}{3}y+\frac{7}{3}$

The standard form of linear equation is:

$Ax+By = C$

In order to convert the given equation in standard form

Multiplying both sides by 3

$3x = -5y+7$

Adding 5y on both sides

$3x+5y = -5y+5y+7\\3x+5y = 7$

Hence,

The given equation in standard form is:

$3x+5y=7$

An isosceles triangle has base angles that each measure 42 degrees.Which equation can be used to find z, the measure of the thir

gavmur [86]

Answer:

z+42+42=180

Step-by-step explanation:

Since it is an isosceles triangle, the two base angles are the same and remember all the angles add to 180. So use this equation:

z+42+42=180

If you need to find z, it is 96.

Check: 96+42+42=180

juin [17]

Answer:

72 maneiras

Step-by-step explanation:

O que acontecerá aqui é que um de cada tipo de roupa será selecionado.

Das 6 camisas, 1 será selecionada O número de maneiras pelas quais podemos fazer isso é 6C1 = 6

Das saias também, ela estará selecionando uma O número de maneiras que isso pode ser feito é 4C1 = 4

O terceiro é selecionar um par de sapatos de 3 e isso seria 3C1 = 3

assim o número de maneiras pelas quais ela pode fazer as seleções é 6 * 4 * 3 = 72 maneiras

For each pair figures, find the ratio of the area of the first figure to the area of the second. 14mm 7mm

Paraphin [41]

The ratio of the area of the first figure to the area of the second figure is 4:1

<h3>Ratio of the areas of similar figures </h3>

From the question, we are to determine the ratio of the area of the first figure to the area of the second figure

The two figures are similar

From one of the theorems for similar polygons, we have that

If the scale factor of the sides of two similar polygons is m/n then the ratio of the areas is (m/n)²

Let the base length of the first figure be ,m = 14 mm

and the base length of the second figure be, n = 7 mm

∴ The ratio of their areas will be

$(\frac{14 \ mm}{7 \ mm})^{2}$

$= \frac{196 \ mm^{2} }{49\ mm^{2} }$

$=\frac{4}{1}$

= 4:1

Hence, the ratio of the area of the first figure to the area of the second figure is 4:1
